HEAD-PROTECTING RESPIRATOR.

SPECIFICATION forming part of Letters Patent No. 437,995, dated October7, 1890.

Application filed June 3, 1890. Serial No. 354,128. (No model.)

To all whom it may concern/.

Be it known that I, J ENS O. JENSEN, a citizen of the United States ofAmerica, residing at Denmark, in the county of Lincoln and State ofKansas, have invented certain new and useful Improvements in HeadProtectors, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to an improved headprotectorforusebythrashing-machine attendants, and it has for its object theproduction of improved means for protecting the head from dust and inproviding a free circulation of air within the helmet.

The invention consists in a cap or helmet having front viewing-points,an inner flexible band for fitting snugly on the wearers head, andprovidinga continuous space or passageway terminating in an upperopening and a rear opening for admission of air, which is directed inits passage by a movable cowl or vane, substantially as hereinafterfully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of myimproved head-protector. Fig. 2 is a vertical longitudinal sectionalview thereof. Fig. 3 is a horizontal sectional View on the line x as,Fig. 1. a rear elevation.

Referring to the drawings, A designates the cap or helmet made of wireframe, having a covering a of any suitable material. The upper end ofthe cap or helmet has a hole or opening a formed therein. The lowerfront extension a of said cap orhelmet is provided with twosight-openings covered with isinglass a A lowerextension orneck-covering B is secured to the lower edge of helmet A, and the sameis provided with draw-strings b, by which it is drawn in around the neckof the wearer.

O is a flexible band having an inner padded face 12. The ends of thisband are adj ustably connected together by a stud 12 of one end enteringany one of a series of holes or slots 17 in the other end. A series ofcoil-springs D, placed at suitable distances apart, are connected toband 0 at their inner ends, their outer ends being secured to the lowercircular wire of the helmet-frame. By this means the Fig. 4 is protectoris made so as to fit different sizes of heads, and a space is alwayspreserved between the head of the wearer and the helmet.

In the rear portion of helmet A is an opening E for the admission ofair, the same being directed thereto by a deflector e, the ends of whichdiverge outwardly some distance.

F is a cowl or vane pivotally connected by a rod or pin f in the outercentral portion of deflector e, the inner end f of said cowl or vanecorresponding in shape to the inclination of said deflector. By means ofa rod f connected to the outer end of cowl F, the same can be moved soas to throw its inner end from one side of openingE to the other, and inthis manner the air which is caught by said cowl is readily conveyedthrough said opening, the cowl being moved according to the direction ofthe wind. lVhen the latter is blowing directly toward the opening anddeflector, the cowl or vane is unnecessary, and can be removed.

The advantages of my invention are apparent, and it will be seen that inaddition to providing a covering and protector for the head of anoperatorI also insure a free circulation of air, no matter in whatdirection the wind may be blowing.

I claim as my invention-- 1. A head-protector having an upper opening, acontinuous space or passage-way, arear air-opening, and a movable cowlor vane, substantially as set forth.

2. In ahead protector, the helmet havingan upper opening, a continuousspace or passageway, a rear opening, and adeflector, the movable cowl orvane having its inner end located in said deflector, the pivotal pintherefor, and the rod connected to the outer end of said cowl or vane,substantially as set forth.

3. In a head-protector, the helmet having the wire frame, the flexibleband having its ends adjustably connected, and the coilsprings connectedto said band and to said frame, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
